ZyXEL Communications NWA-3160 - V3.70 Manual page 219

PEAP (Protected EAP) and MD5 authentication is implemented on the internal
RADIUS server using simple username and password methods over a secure TLS
connection. See
authentication and the internal RADIUS authentication method used in your NWA.
Note: The internal RADIUS server does not support domain accounts (DOMAIN/
user). When you configure your Windows XP SP2 Wireless Zero Configuration
PEAP/MS-CHAPv2 settings, deselect the Use Windows logon name and
password check box. When authentication begins, a pop-up dialog box
requests you to type a Name, Password and Domain of the RADIUS server.
Specify a name and password only, do not specify a domain.
